Transmission for a road vehicle with hybrid propulsion

摘要

Transmission (7) for a road vehicle (1) with hybrid propulsion; the transmission (7) comprises: a gearbox (10) provided with one primary shaft (15), one secondary shaft (19, 20) and at least one pump (25, 26) actuated by an activating shaft (27); at least one clutch (17) connected to the primary shaft (15) and presenting a part which is normally conductive which can be connected to a drive shaft (6) of a thermal engine (5); at least one reversible electric machine (8) presenting a shaft (23) mechanically connectable to the primary shaft (15); a first mechanical transmission (28) which transmits motion from the normally conductive part of the clutch (17) to the activating shaft (27); and a second mechanical transmission (30) which transmits motion from the shaft (23) of the electric machine (8) to the activating shaft (27).
